The invention provides a torque zero-crossing control method and device, a medium and equipment. The torque zero-crossing control method comprises the steps that a sudden change signal of a vehicle accelerator pedal is obtained; based on the abrupt change signal, the initial torque of the vehicle before abrupt change and the target torque after abrupt change are obtained; calculating a first intermediate torque and a second intermediate torque of the vehicle based on the transition torque; controlling a driving mechanism of the vehicle to output torque according to a separation stage, a transition stage and a combination stage; when the torque direction of a driving mechanism of a vehicle changes suddenly, a transition torque is determined according to vehicle state information, a first intermediate torque and a second intermediate torque are calculated, and the torque sudden change process of the driving mechanism of the vehicle is divided into a separation stage, a transition stage and a combination stage. And the torque change slope of the transition stage is set to be smaller than the torque change slopes of the separation stage and the combination stage, so that the phenomena of torque zero-crossing impact, tooth knocking and the like are relieved as much as possible on the premise of ensuring the timeliness of the sudden change of the torque of the vehicle driving mechanism.

    本申请提供了一种扭矩过零的控制方法、装置、介质及设备,获取车辆加速踏板的突变信号;基于突变信号,获取车辆在突变前的初始扭矩和突变后的目标扭矩;基于过渡扭矩,计算车辆的第一中间扭矩和第二中间扭矩;控制车辆的驱动机构按照分离阶段、过渡阶段和结合阶段输出扭矩;即在车辆的驱动机构的扭矩方向突变时根据车辆状态信息确定过渡扭矩并计算第一中间扭矩和第二中间扭矩,将车辆驱动机构的扭矩突变过程划分为分离阶段、过渡阶段和结合阶段,并且将过渡阶段的扭矩变化斜率设置为小于分离阶段和结合阶段的扭矩变化斜率,在保证车辆驱动机构扭矩突变的时效性的前提下,尽量缓解扭矩过零的冲击、敲齿等现象。
